More late-caught fallout from the mainline merge. The patch:
[POWERPC] Use archdata.dma_data in dma_direct_ops and add the offset
"Now that all platforms using dma_direct_offset setup the
archdata.dma_data correctly, ..."
Nope -- the pasemi iommu setup code that disables translation on the
DMA pci device didn't set dma_data correctly.
The below patch is needed, please merge as soon as practical. Thanks!
